When ages are in a ratio like 3:4:5, it means that for some common unit of age, the first man has 3 units, the second has 4 units, and the third has 5 units. We don't know the exact size of this unit. The variable x represents this common unit or multiplier. If x is 1 year, the ages are 3, 4, and 5 years. If x is 10 years, the ages are 30, 40, and 50 years. By using 3x, 4x, and 5x, we ensure that the ages maintain the given ratio while allowing us to find their actual values. Got more? Send 'em.
